Physical evaluation of a new pulp capping material developed from portland cement.

MTA (14.67±1.53 min) showed the lowest statistical mean Initial setting time (Min) compared to Portland cement + bismuth (43.60±6.61 min), Port Cal I 10 wt% (41.55±3.60 min) and Port Cal II 25 wt% (40±2.35 min) with only a highly significant difference between MTA and all other tested materials at P ≤ 0.001.
